Disconnecting a Citrix Session with CTXDiscon

Windows has a command line tool which allows you to disconnect any RDS Session. The command line tool is “TSDISCON”, available in the System32 folder. Now, if you have connected using XenApp or XenDesktop, this tools does work. However, the Citrix Client will not know that the session has been disconnected, thus the Citrix Client window will remain active on the client’s end device.

There is no built-in tool from Citrix which has the same functionality as TSDISCON has. So I compiled a little tool which allows you to disconnect your Citrix sessions.

ICA connections using PowerShell – Part 4

It has been a while since I last posted something here. And in my previous post in the ICA-PowerShell series, I mentioned doing another post about simulating keyboard and mouse. To sum up, part 1 was about the ICO Object basics, part 2 was about controlling the ICA session appearance and in part 3 I talked about using the ICO Object’s events.

Enabling Simulation API

The ability to control the mouse and keyboard in an ICA session is not enabled by default. For this to work, you will need to enable the Simulation API. This is done by adding a registry key to the machine you will be using:


The “CCM” subkey doesn’t exist by default, so you should create it. If you’re using a 32bit platform for testing, the registry key should look like this:

ICA connections using Powershell – Part 3

In part 1 of this series, I talked about the basics. Part 2 was about the overall session appearance. This part will be about using the events which are available in the ICO SDK. The ICO SDK has a lot of events we can use, but we will be talking about a few so that you get a basic idea on how to use them.

Available Events

First of all, let’s start with the code we use to view all events in the ICAClientClass. We already had the following code:

[System.Reflection.Assembly]::LoadFile("C:\Program Files (x86)\Citrix\ICA Client\WfIcaLib.dll")
$ICA = New-Object WFICALib.ICAClientClass
$ICA.Address = "XASRV001"
$ICA.Username = "TestUser01"
$ICA.Domain = "LAB"
$ICA.Application = ""
$ICA.Launch = $true
$ICA.OutputMode = [WFICALib.OutputMode]::OutputModeNormal
$ICA.DesiredHRes = 1024
$ICA.DesiredVRes = 768
$ICA.DesiredColor = [WFICALib.ICAColorDepth]::Color16bit

This will connect an ICA session. To view all event available, we can use the following code:
